Blackboard must have pop-up blockers disabled to allow all content to work properly.
By default, Chrome will notify you when a pop-up is blocked and give you an option to see it. To turn off the pop-up blocker, follow these instructions:
To disable the pop-up blocker on all sites, uncheck the Block pop-up windows box below Permissions.
To allow pop-ups on specific sites, click Exceptions and enter the URL(s) to allow pop-ups.
To disable the pop-up blocker on all sites, turn the tobble next to Block off (it will be grey when off, blue when on).
To allow pop-ups on specific sites, in the Allow section, click Add and enter the URL(s) to allow pop-ups.
To allow specific pop-ups, navigate to the web page, follow steps 1-3 and then select Allow next to the name of the site.
